I occasionally write some small PHP scripts as games or forums. However, I really need to get involved in a big project. I am a 3rd year CS major and I do not have a job yet. I have tried websites like sourceforge, but I find them not rigorous enough. One option is to team up with my friends from college to create a project; however, I am not that social.
For example, I admire the browser RPG game called Dragon's Call. There is no chance that I can create a similar game by myself. However, I really like to get involved in such a project. How do such projects emerge?
